Crafting
If your crafting skills are not maxed yet, sure you can train these... but crafting in WAR is very, very easy so that won't last long. You can start to hunt for ingredients, but you don't really need to as there are only few consumables you really need. I always run around with stacks of those potions i can use for tanking, but neither is it hard to hunt for them nor is grinding mats that much fun. In WAR there is no real hunt for recipes either, so being busy trying to acquire that odd recipe you're missing is not an option. The pre-launch proclaimed "experimental" side for crafting does not really exist in WAR.
You could try to earn money with your crafting skills, but at the moment crafted things like potions are worth pretty much nothing. Talisman makers can make a few bucks and sure you can sell raw ingredients, but nothing really gives you the "feeling" you created something valuable that is worth selling and showing off proudly at the auction house. Crafting in WAR right now is not a fun experience once you get the hang of it and the "products" are only of limited use. The ingame economy is quite broken compared to other games.
Solo Content
Once you hit rank 40 there are not many quests still worth doing. Most likely you'll have solved all existing epic quests with rank 37 or right after. Why not have some loooong and epic rank 40 questline to immerse in? In Age of Conan you had this very long and character defining main quest line you were following all the way up to max. level. Some epic rank 40 questlines with a good story to tell, a few nice rewards along the way and some epic challenges would be great. In AoC there were many instances for that questline you had to enter solo and no one else could help you with. Some of them had good challenges concerning the appearing fights and you had to utilize your character properly to beat them. Talking about those instances, why not have a duo dungeon? I know many play with their girlfriend/wife or best friend. A challenging dungeon for two players could be fun as well. Could be like an epic PQ, maybe 30-40min long, repeatable once a day. And i really don't care if you can only find social clothing in there, just want something unique.
Tome unlocks
Of course there are tome unlocks you can hunt as well. But most are pretty useless when it comes to character development and just fluff. I like fluff, but killing thousands of NPCs (for the unlocks not everyone has) is not that much fun. And once you scouted the existing world there is not so much more to see.
